liquid mixers

33, 43, 53 for detecting the amount of ozone gas flowing through the

air inlets

35, 46, 56 per unit time, and The detected data is transmitted to the bathroom controller 20, the room controller 40, and the kitchen controller 50.

When the ozone supply system is in operation, the user can control the opening and closing of each solenoid valve through the control keyboards 17, 18, 19, thereby controlling the ozone supply of each air supply outlet. In this way, the user can control the opening and closing time of the specific solenoid valve according to the actual amount of ozone used, and the supply of ozone is not directly related to the discharge of the water flow, and the supply of ozone is more flexible.

In addition, the faucet of the embodiment may be a faucet disclosed in the utility model patent CN201628015U, the faucet includes a faucet body and a faucet sleeve, and the faucet sleeve is provided with a drawing hose, and the length of the drawing hose is much longer than the faucet.

Since the water regulating valve is provided in the main body of the faucet, the tap water and the ozone gas can be separately discharged through the drawing hose.

In this way, when the user needs to use tap water, the solenoid valve in the pipeline for supplying ozone gas can be turned off, and the water regulating valve can be turned on to use the tap water. If the user needs to use ozone gas alone, the water quantity regulating valve can be closed, and the electromagnetic valve can be opened to obtain ozone gas by pulling the end of the hose.

In addition, the present embodiment can also use the signal output from the water flow sensor as a signal to close the solenoid valve. Referring to Figure 2, when the ozone supply system is in operation, the central processing unit performs step S1 to drive the ozone generator to operate, and the ozone generator generates ozone gas and delivers it to the pipeline. Then, the controllers such as the bathroom controller, the kitchen controller and the room controller determine whether the water flow sensor detects the water flow signal, that is, step S2 is performed, and if the water flow signal is detected, step S3 is performed to open the corresponding water flow sensor. The solenoid valve corresponding to the water inlet pipe, the ozone gas in the pipe is formed into an ozone water supply through the electromagnetic valve flow inlet liquid mixer.

In this embodiment, the signal outputted by the water flow sensor to the bathroom controller is used as a signal for opening the electromagnetic valve. In actual application, the user may input control information of the electromagnetic valve through the control keyboard, such as inputting information of the opening solenoid valve 27, The opening signal is output from the toilet controller to the solenoid valve 27, which also enables control of the solenoid valve.

Then, the gas flow controller in the gas-liquid mixer with the solenoid valve turned on detects the amount of ozone gas flowing through the gas-liquid mixer inlet per unit time, the controller of the bathroom controller, the kitchen controller, and the room controller. Step S4 is performed to determine whether the amount of ozone gas flowing through the air inlet per unit time is greater than a flow rate threshold of the corresponding water terminal. If not, the determination continues. If it has been exceeded, step S5 is performed to issue a reduced solenoid valve opening. The signal, the opening of the solenoid valve is reduced to reduce the flow of ozone gas flowing through the air inlet per unit time.

Finally, the bathroom controller, the kitchen controller and the room controller determine whether the water flow signal detected by the water flow sensor disappears, that is, step S6 is performed, and if the water flow signal disappears, the water terminal such as the faucet is closed, and the controller sends the corresponding solenoid valve. Turn off the signal and stop supplying ozone gas to the gas-liquid mixer.

It can be seen from the above scheme that the smart home system can supply ozone gas to a plurality of water terminals only by providing an ozone generator, which can greatly improve the convenience of using ozone in the home. Moreover, it is not necessary to provide a power outlet near the water terminal such as a faucet, and it is possible to avoid an accident caused by water splashing on the power outlet.

Water leakage prevention system:

Referring to FIG. 3, the smart home system further includes a plurality of mobile sensors connected to the central processing unit 10, including a toilet movement sensor 66 disposed in the bathroom, a kitchen movement sensor 67 disposed in the kitchen, and the like. Of course, in practice, more mobile sensors can be installed in the house.

The motion sensor detects the human body's signal and the human body's activity signal by including infrared detection and microwave detection. If there is human activity in the detection area of the motion sensor, the motion sensor detects the human body activity signal and transmits it to the central processing unit 10. If the human body is inactive for a long time in the detection range of the motion sensor, the motion sensor detects that a person exists within the detection range, but does not move for a long time. If there is no human activity within the detection range of the mobile sensor, the mobile sensor will not detect the human body's signal, including information such as the body temperature that cannot be detected.

The water leakage prevention system further includes a solenoid valve 61 disposed in the inlet water inlet conduit 68 and a water flow sensor 62 located upstream of the water flow sensor 62 in the inlet water inlet conduit 68.

In addition, the central processing unit is also connected to the input device, and the input device includes a solenoid valve reset button 69. When a large amount of water is stored for a long time and there is no human activity in the bathroom or the kitchen for a long time, the central processing unit 10 may misjudge the bathroom or the kitchen. There is a large amount of tap water flowing without a person, and the solenoid valve 61 may be erroneously closed, so a manual reset reset button 69 is required to manually reset the solenoid valve 61.

A memory-free duration threshold is stored in the memory 11 of the central processing unit 10. After the mobile sensor does not detect that the human body signal exceeds the threshold, it is determined that there is no person in the bathroom or the kitchen.

When the water leakage prevention system is in operation, the water flow sensor 62 detects the flow of water in the inlet water inlet pipe 68. If tap water is detected, it indicates that water leakage may occur. At this time, the toilet movement sensor 66 operates with the kitchen movement sensor 67, detects a human body activity signal, and transmits the detected human body activity signal to the central processing unit 10. If the central processing unit 10 determines that the bathroom movement sensor 66 and the kitchen movement sensor 67 have not detected the signal of the human body for a long time, it is determined whether the time when the motion sensor does not detect the signal of the human body is longer than a preset threshold value of the duration of the non-human body signal, if If it is longer than the water leakage condition, the central processing unit 10 sends a closing signal to the solenoid valve 61, and the solenoid valve 61 is closed to prevent water leakage.

Of course, if the central processing unit 10 receives the human activity signal within the length of time without the human body signal duration threshold, the current timing is terminated, and the time is restarted after the mobile sensor does not detect the human body signal. When the water flow signal detected by the water flow sensor 62 disappears, the toilet movement sensor 66 and the kitchen movement sensor 67 can be stopped.

After the central processor 10 determines that a water leakage condition has occurred, the buzzer 64, 65 emits an audible and visual alarm signal, and the wireless transmission module 68 can also issue a wireless alarm signal, such as dialing a specific telephone number, issuing a specific short message, and the like.

Of course, the water flow sensor can also be installed on the water inlet pipe connected to each water terminal, so that it can more accurately detect which water terminal is forgotten to close, or which pipe is broken.

Falling alarm system:

Referring to FIG. 4, the embodiment includes a plurality of sensors such as a toilet movement sensor 66, a kitchen movement sensor 67, a stair movement sensor 71, and a room movement sensor 72 connected to the central processing unit 10 for detecting an activity signal of a human body. The fall alarm system further includes an alarm device such as a buzzer 64 and an LED lamp 65, and a wireless transmitting module 68 connected to the central processing unit 10. Further, the memory 11 of the central processing unit 10 stores a human body stationary time threshold for determining whether a person has fallen.

After the fall alarm system is started, a plurality of mobile sensors such as the toilet movement sensor 66, the kitchen movement sensor 67, the stair movement sensor 71, and the room movement sensor 72 detect the human activity signal in real time, and transmit the detected signal to the central processing unit 10 . After receiving the signal transmitted by the mobile sensor, the central processing unit 10 determines whether the human body is stationary for a long time. If it is determined that the human body is stationary for a long time, it is determined whether the static time of the human body is longer than the threshold value of the human body static time, if it is longer than Indicates that a person may fall, and an alarm signal is issued, including dialing a specific telephone number through the wireless transmitting module 68, issuing a specific short message, and the like.

After the central processor 10 determines that a person has fallen, it can also issue a closing signal to the electromagnetic valve located in the water inlet pipe of the household to turn off the water outlet of the water terminal such as the faucet to prevent the falling person from being drowned.

Of course, when people take a bath for a long time or sleep at night, they may stay in the bathroom or the room for a long time. Therefore, the fall alarm system also has a switch button 70 connected to the central processing unit 10, and people can press the switch button. 70 to close the fall alarm system to avoid system false alarms.

Children's anti-fall system:

Referring to Fig. 5, the child fall prevention system has a signal generator placed on the child, such as a magnetic substance such as the magnet 81 of the present embodiment, and a signal receiver is placed on a dangerous area such as a balcony, a window, a mezzanine corridor, for example. The magnetic sensor 82, the magnetic sensor 82 transmits the received signal to the central processing unit 10 by wire or wirelessly.

The memory 11 of the central processing unit 10 stores a duration threshold, which is a threshold value of the length of time that the signal receiver receives the signal from the signal generator, when the magnetic sensor 82 receives the magnetic field signal from the magnet 81. The length of time is longer than the threshold of the duration, indicating that the child is active in the dangerous area for a long time, and there may be an accident of falling down, so the central processing unit 10 will send an alarm signal and take rescue measures.

In this embodiment, the central processing unit 10 is connected with an audible and visual alarm device such as a buzzer 64 and an LED lamp 65, and is also connected with a remote alarm device such as a wireless transmitting module 68. When the central processing unit 10 receives a signal such as the magnetic sensor 82. After the signal transmitted by the receiver, it is judged whether the signal received by the signal receiver from the signal generator is longer than the duration threshold, and if it is longer, the alarm signal is sent, including dialing a specific telephone number through the wireless transmitting module 68 or to a specific The mobile number sends a short message.

In addition, the embodiment further includes a power window controller 83 connected to the central processing unit 10, the power window controller 83 is mounted on the power window, and the power window has the function of automatically closing the window, and the power window can be used as the announcement number CN201605943U. The utility model discloses a power window. When the central processing unit 10 determines that the child may be in danger of falling off the building, the central window controller 10 sends a window closing signal to the power window controller 83, and the power window is automatically closed to prevent the child from falling down.

Of course, the signal generator is not limited to the use of a magnet, but may also be a radio frequency signal generator, and the corresponding signal receiver is a radio frequency signal receiver.
